Exploring Patterns and Sequences with Decimals

This video tutorial covers patterns and sequences with decimals, explaining how to identify and apply pattern rules using addition and subtraction. It demonstrates extending sequences, finding missing terms, and solving practical problems involving money. The tutorial emphasizes the importance of comparing terms to determine consistent rules and highlights the use of mixed operations in complex patterns.

What is each number in a sequence called?

• A digit

• A variable

• A factor

• A term

What mathematical operation is primarily used to find missing terms in a sequence?

• Addition

• Division

• Subtraction

• Multiplication

What does an ellipsis in a sequence indicate?

• End of sequence

• Irregular pattern

• Error in sequence

• Continuation of the pattern

What is the pattern rule when the sequence increases by 1.1 each term?

• Multiply by 1.1

• Divide by 1.1

• Subtract 1.1

• Add 1.1

How do you standardize decimals for comparison in sequences?

• Round them off

• Add trailing zeros

• Multiply by 100

• Convert to fractions

What does a sequence with no pattern imply about its rule?

• The rule is inconsistent

• The rule involves multiplication

• There is no rule

• The rule is complex

What rule involves both addition and subtraction in a sequence?

• Subtract 1.7 continuously

• Add 0.6, add 0.6, subtract 0.3

• Add 0.6, subtract 0.3

• Add 1.5, subtract 0.3

In a sequence, if the rule is to start at 4.25 and add 1.25, what is the second term?

• 5.25

• 5.75

• 6.25

• 5.50

How much money does Su Jin have left after five days of bus fare?

• $12.45

• $7.20

• $16.20

• $10.25

What indicates a pattern in a sequence?

• Same difference between each term

• Different differences between terms

• Decreasing terms

• No visible changes
